Where and when glass production began is uncertain. It is thought by some that the first glass was probably developed in the Mitannian or Hurrian region of Mesopotamia, possibly as an extension of the production of glazes (*5000 BCE) [1]. Around this same time, a new material called faience was developed, which was produced by utilizing a variety of techniques to create a glaze layer over a sil...

Background: Odontogenic tumors are derived from the epithelial and/or mesenchymal remnants of the tooth-forming apparatus. Therefore, they are found exclusively in tooth-bearing areas. Similar to other neoplasms in the body, odontogenic tumors tend to histologically mimic the cell or tissue of origin. Case history: A 5-year-old boy presented with a chief complaint of pain in the mandible whi...

In August 1992, a physician notified the Alaska Division of Public Health (ADPH) that three patients at a psychiatric hospital had consumed ceramic glaze during ceramic therapy (i.e., recreation therapy involving the production of ceramic ware), and two of these patients had elevated blood lead levels (BLLs). This report summarizes the ADPH's investigation of these ingestions.

Icing is widely recognized as one of the most serious weather hazards to aircraft operations. Aircraft icing occurs when small, super-cooled, airborne water droplets, which make up clouds and fog, freeze upon impact with a surface, which results in the formation of ice (Mason 1971). The freezing can be complete or partial, depending on how rapidly the latent heat of fusion can be released into ...

The color of 7 composite resins, an unfilled restorative resin, and 3 glaze coatings was determined by reflection spectrophotometry and visually with Munsell color tabs. Statistically significant correlations existed between comparable parameters of the spectrophotometric and Munsell data. There was observable color variations among the 11 resins studied, but only 3 materials were within the ra...

The Mesopotamian invention of suspended narratives in mineral pigment and glaze produced in the fifteen thousand year old ‘new technology’ of the ceramic tile sets the scene for my talk for EVA 2010 (and this published paper which is intended to act as a prologue to that talk). It was this invention, a mass-produced media technology with the limit of a prototype glass screen that allowed commen...

OBJECTIVE This study tested whether the two-body wear of monolithic zirconia and their corresponding enamel antagonists was higher compared to monolithic alloy and veneered zirconia. MATERIALS AND METHODS Cylindrical specimens (N = 36, n = 6) were prepared out of (A) veneered zirconia (VZ), (B) glazed zirconia using a glaze ceramic (GZC), (C) glazed zirconia using a glaze spray (GZS), (D) man...
